TOY LADDER-TRUCK.

Specification of Letters Patent.

Patented June 12, 1913.

Application filed July 22, 1916. Serial No. 110,758.

To all whom it may concern.

Be it known that I, HARRY T. KINGSBURY, a citizen of the United States, residing at Keene, in the county of Cheshire, State of New Hampshire, have invented certain new and useful Improvements in Toy Ladder- Trucks, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

My invention relates to improvements in toy ladder trucks. 7

An object of my invention is to provide a ladder truck of this character driven by amotor and in which the ladders are normally held in a horizontal position and are automatically raised, upon the forward end of the truck coming in contact with an obstacle and is held in said raised position until lowered by hand.

A further object of my invention is to provide a ladder truck in which the ladder and its raising means are of a simple construction whereby the toy can be cheaply manufactured and having certain details of structure and operation hereinafter more fully described.

In the accompanying drawings Figure 1 is a side elevation of my toy ladder truck showing the ladder sections in their lowered position;

' Fig. 2 is a top plan view of Fig. 1;

Fig. 3 is a side elevation, showing the ladder sections in their raised position; and

Fig. 4 is an enlarged sectional view of-the hinge connection betweenthe ladder sections.

Referring now to the drawings, 1 represents the frame of my improved truck which is preferably of U-shaped form and sup ported at its rear end by the plate 2 secured to the upper face of the motor casing 3. The motor casing on its lower face is provided with ears in which the axlel of the rear wheels 5 is mounted and said axle is driven by the motor, all of which is well understood and needs no further description.

The forward end of the U-shaped frame 2 is provided with the plate 6 having downwardly extending ears 7 in which is mounted the forward axle 8 carrying the wheels 9. While I have shown this specific form of frame for supporting the wheel, it will be understood that the same could be varied without departing from the invention.

The forward end of the frame 1 is provided with a seat supporting frame 10 carrying the seat 11 and the steering column 12. The frame 10 has in rear of the seat 11 the upwardly extending cars 13 and ll in which is mounted a shaft 16. Pivotally mounted upon the shaft 16 is a ladder truck section. 17 which is normally in a horizontal position and has its outer end resting upon the plate 2, as clearly shown in Fig. 1 of the drawings. Secured to theouter end. of the ladder section 17 is a plate 18 which is provided with outwardly extending cars 19 in which is secured the shaft 20 and the plate having a tongue 21 bent around the rung 22 of theladder section 17.

The outer ladder section 23 has a plate 24 secured to the inner end which has ears 25 through which the shaft 20 passes and by means of which the two ladder sections are pivoted together so that their ends 26 and 26 abut when the ladders are in their extended position as clearly shown in Fig. 3 of the drawings. The plate 24: has tongue 27 bent around the rung 28 of the ladder section 23 and whereby the plate is secured to the ladder section.

Pivotally mounted .upon the shaft 16 is a plate 29 which extends between the ears 13 and 14 and extends vertic'allv a considerable distance above the ears. Slidably mounted upon the frame 10 is a wire loop 30 which has a reduced forward end 31 passing through a slot 31 in the frame 6. The

rear end of the wire loop has its ends turned laterally at 32 and entering the bifurcated ends 33 of the plate 29 and whereby the plate is rocked upon thepivot for the purpose hereinafter more fully described.

Secured to the tongue 27 of the plate 24L is an L-shaped plate 34: which'has secured thereto a coil spring 35 which has its opposite end secured to the plate 29 at the central cutaway portion at 36 as clearly shown in Fig. 1 of the drawings. The spring as shown normally is exerting a forward pressure on the upper ladder section 23 which holds the rung 37 in the notches 38 of the bifurcated upper end of the plate 29 and whereby said upper and lower sections are held in a horizontal position.

In the operation the truck is driven by the motor and upon the looped end 31 of the loop 30 striking an obstacle such as the wall or the like, forces the loop 30 rearwardly rocking the plate 29 on the pivot 16 forcing the upper end carrying the notches away from the rung 37 and releasing the same. The spring 35 draws on the L-shaped plate 3st and the same being fulcrumed on the shaft 20 forces the outer ladder section 23 upwardly and outwardly into a position approximately horizontal. After reaching this position the L-shaped plate 35 bears upon the plate carried by the laddersection 17 and throws the ladder section 17 into an approximately vertical position as shown in Fig. 3 of the drawing. It is ul'iderstood that the ladder is moved downward and latched by hand.

It is obvious that minor changes in the details of construction and arrai'igemeiit of parts, should be made without departing from the spirit of the invention as set forth in the appended claims Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is 2- 1. A toy ladder truck, comprising aladder pivoted thereto and formed of pi'votally connected sections, a catch for holding the ladder sections in their folded lrorizontal position, and a spring connected to the inner end of the outer section below its pivot and normally holding the sections in their extended vertical position. v

2. A toy ladder truck, comprising aladde'r pivoted thereto and formed of pivotally conne'ct'ed sections, a catch for holding the ladder sections in their folded horizontal position, and a spring coniiected to the latch and the inner end of the outer ladder section below its pivot with the other section and normally holding the sections in their exteli' ded vertical position.

3'. A toy ladder truck, comprising a ladder pivoted thereto and formed of pivotally connected sections, an intermediately pivoted catch engagiiig the rung of the outer section of the ladder and holding the sections in their folded horizontal position, and a spring normally holding the sections in their extended vertical position.

4. A toy ladder truck, comprising a ladder pivoted thereto and forn'ied of pivotally con nected sections, an intermediately pivoted catch engaging the rung of the outer section of the ladder and holding the sections in their folded horizontal position, a spring normally holding the sections in their extended vertical position, and means for releasing the catch and extending beyond the forward end of the truck.

5.
